how to format /dev/sda in linux


Hello,

I wonder how I can format drive in Linux. What tools would I need?.
Can be command line ones.
Installed qtparted, it runs but critical error shows up.
"Cannot read disk". I have no fdisk but it would allow me only to set up
partitions for the formatting. I want to format one partition without
changing the set up of them.

Cheers

What filesystem type are you wanting to format it to? for ntfs fs it is recommended to use windows based tools.

Otherwise

mkfs -t fat /dev/sda
or
mkfs.fat /dev/sda works in most cases
or

sudo mkfs.vfat -n ‘Label’ -I /dev/sda

But I have no mkfs. This is 64-bit Fedora and there are no such tools like
fdisk or mkfs. Neither in normal user nor su. Maybe therea are some other tools which this system have?.

Where are you reading that their is no mkfs for x86_64?

try /sbin/mkfs

mkfs is the standard linux tool for creating filesystems, I do not use the 64-bit version, but I don't see why they would have removed it.

With this command I can format drive to fat32?. Because this is what I want. I cannot format this partition from windows. In windows formatting goes on well till 100% than it says that the disk cannot be formatted.
Tried Partition Magic 7.0 and 8.0 but to no avail. It just won't start.

ok so you found mkfs? please answer the questions asked so you can be helped correctly.

If you can format it in windows try doing a quick format. Otherwise mkfs -t fat is the command you need to use.

You do not need partitioning software just to format a drive.
if your getting can't read errors you may have other issues, bad sectors, or corrupted partition.

Also make sure the drive is not mounted while you are trying to use mkfs on it.

I have no access to the computer in question, but I asked question from
previous post in advance. Quick format doesn't work as well. This is new
disk so I don't suspect there are bad sectors etc. But who knows?.

if its a new disk it may not have a partition to format on it. These are all things that would have been good to know from the beginning, I guess its my fault for not asking.

As you do not have access to the machine I don't know what else to suggest.

Yes, it's a new disk but already partitioned. It has 6 partitions and one of them cannot be formatted. I loose 80GB. On one of them there is windows, on some other Fedora. I tried to format from windows: no success. So now I try to format on fat32 from Fedora. I think the situation is now clear.

OK, I've checked, there is fdisk and mkfs, as you suggested, in /sbin directory. But command /sbin/mkfs -t fat /dev/sda6 (in my case) doesn't work, it says something like that: "mkfs.fat: No such file or directory".
With ext2 as a parameter program runs, but not when there is fat or fat32(checked that also) as a parameter.

Thanks for help. I couldn't reply earlier. Partition is now seen, readable and writable in windows.

try downloading ntfstools, the package includes tools to format ntfs, resize ntfs filesystems, clone ntfs filesystem and others.
